| 摘 要： | 旨在克隆内蒙古白绒山羊血管内皮生长因子(vascular endothelial growth factor,VEGF164)基因并分析其基本表达模式。采用RT-PCR技术克隆基因,将得到的基因cDNA序列及其编码的氨基酸序列进行生物信息学分析。利用半定量RT-PCR方法进行组织表达检测。获得了内蒙古白绒山羊VEGF164基因编码区cDNA全长序列,扩增片段全长573 bp,包含了完整的ORF,编码190个氨基酸残基。核苷酸序列与绵羊的VEGF164(EU857623.1)基因同源性为99%,相应的氨基酸序列同源性为99%。SMART程序分析表明,ORF编码的蛋白质具有信号肽序列及血小板衍生和血管内皮生长因子家族(PDGF,VEGF)结构域。Psite程序分析表明,有1个蛋白激酶C磷酸化位点,4个酪蛋白激酶磷酸化位点。ProtComp Version 9.0程序分析将其定位于细胞外。RT-PCR检测表明,VEGF164基因在绒山羊脑、心脏、睾丸、胰腺、脾、肾和肺组织中均有表达。
